In an excited hydrogen atom, when the electron jumps from nth energy level to (n-1)th energy level, wavelength of emitted radiation is λ, when the electron jumps from (n-1)th energy level to (n-2)th energy level, wavelength of emitted radiation is Kλ. Then what will be the wavelength of emitted radiation when the electron jumps from nth energy level to (n-2)th energy level?
